Introduction to Image Arithmetic

An ``image'' may be either a 2-D image array or a 1-D spectrum vector. The commands for one- or two-image arithmetic are:

\item[ADD\hfill]{add two images or an image and a constant.}
\...
...m[NINT\hfill]{nearest integer}
\item[ONEOVER\hfill]{invert (1/x)}
\end{example}
